Folks,
 
 Its always fun to work with Powershell such a simple and powerful commands for  all sorts of administrative tasks in SharePoint environment. I had to set up my  welcome page in my sharepoint site from the default one to the custom home page  (developed by external vendors).
 
 In this blog, Let me the share the piece of PowerShell Commands thats being used  to achieve this.
 - Add-PsSnapin Microsoft.SharePoint.PowerShell   
 - $w = get-spweb http://mysite.site   
 - $r = $w.RootFolder   
 - $r.WelcomePage = "Pages/CustomHome.aspx"   
 - $r.Update()   
 - $w.Dispose()  
 
Happy SharePointing 
 Please be feel free to add any suggestions/inputs.
